Develop/Single sign on

The OpenStreetMap project would ideally support single sign on across the editing interface, the wiki, and the other systems. Several different types of Accounts are in use. Unification of the logins/accounts would, of course, be a good idea. It has been discussed before, but it's a bit of development effort which hasn't happened yet. There are also complications around policies for changing user name.

OAuth

OAuth may help us to achieve single sign on, although we will still encounter some of the tricky problems with usernames between the two systems. Essentially we will be implementing full on integration, with OAuth as mechanism to pass tokens between the apps. OAuth is something we have implemented on OSM accounts anyway, for other reasons (for authorization of 3rd party apps) Using OAuth for single sign on with the wiki may now be possible
